Abstract
Very high dielectric constants have been observed for bacteria at low frequencies. High dielectric constants such as these can be explained by a theory which has been developed for the low-frequency dielectric dispersion of porous charged particles and which has been tested successfully through measurements with ion exchange resins. The bacterial cell wall is electrically similar to an ion exchange resin. Observations show that the theory provides a quantitative explanation for the low-frequency dielectric dispersion of bacteria.
摘要
在低频下已观察到细菌具有非常高的介电常数。像这样的高介电常数可以用一种理论来解释，该理论是针对多孔带电粒子的低频介电色散而发展起来的，并且已经通过离子交换树脂的测量得到了成功验证。细菌细胞壁在电学上类似于离子交换树脂。观察结果表明，该理论为细菌的低频介电色散提供了定量解释。
